HarrieH's classic track bike projectA track bike has the beauty of simplicity. No distraction of cables, bottle holders, pumps and other accessories. Just a frame, fork, drivetrain, steering components and something to sit on will do the job on a track.
Some parts I already have for decades, others I have to collect. It's fun to look for the right components, to get them, build up the bike and, of course, ride it on the velodrome.
Oh, besides track, lots of (off-)road stuff as well.

Gazelle track, Shimano Dura Ace 10 mm pitch

I bought this Gazelle track frame, 55 cm, for my 2nd Shimano Dura Ace 10 mm pitch group set.
Unfortunately, the geometry is a bit strange (very shallow seat tube angle, long top tube) and too old for both my taste and for the group set. Frame kit is approx. 1968, while the group set is approx. 10 years newer.
Not a great combination, not ridable for my or my son, so I took it apart again.
Here's a full spec.
